Okay, before anyone tries to quickly dispatch me to the "search" function, I have already been there and read them all. This situation may be unique. Please listen to my tale before it rains again.

Tonight I AUTO lowered the drivers window. It went down no problem. When I press the window up button it went up about an inch and stopped. There is clicking with repeated "up" button pressing but no further "up" movment. Press the "down" button the window goes down. I have beaten and banged door handles and door skins while pressing the window button to no avail. Not a good look for a car that dosen't have it's plates yet. Comments anyone?

 

After digging a little deeper I am going to try 2 approaches. Remove the door panel and the window motor then rotate its main gear to a position with undamaged threads. Or just replace the motor all together.

I am going to skip the relay theory as my symptoms don't sound electrical.

What I would like to know is, Can the window motor be access when the interior panel is removed alone or is additional dismantling required. I can't tell from the photos I seen so far.

 

Not a common item but I've had the issue on my sons Camaro

When the motor starts to get old theres a thermal cut out which trips. This causes intermittent operation - move stop, wait, move, stop ......... I plan to replace the motor on the Camaro to fix it.

On the Vette you need to take off the door panel, remove the water deflector, Remove the door speaker, remove the window. At that point you can get at the regulator

Thank you for planning my weekend. I will update in a few days.

 

There are pics that go with that procedure. PM me with your e mail and I can send you a word doc which includes the pics

 

window regulator....

yep, regulator. Did it make clicking and cracking sounds? The regulator is cable driven and when the cable frays, the window stops. The new regulator comes complete, pretty easy to replace and just plug it back in. Yep, it's pricey and no, I havent' found a cheap one. You may be able to get it back up once, but I would get a new one, do it once and be done. Good luck.

 

Mine did that 2 days ago. It was the fuse, The fuse was ok, but the fuse was loose, if that makes since. I got a small flat head and pushed the metal things together. I believe its fuse #34under the foot rest on the pass. side. It works great now! Hope you get it fixed!

 

A window regulator is one of the weak items on all modern cars these days. To save weight and cost mostly, these things are very fragile.

If any problems with clicking or jumping change it. Driver door is always the first to go.

 

This must be my lucky week. The drivers side went out 2 months ago and now the passenger side is out.

 

My driver window on the 2004 Z first starting making noises, and then leaked with the rain we are currently experiencing, big time leak-
The window seems to move a lot inward, like something is broken, and now it will not go up or down at all.... anymore
Lucky it is up.

I looked at threads in the search function- so don't beat on me....

here is my question- I have a $200 decuctible GMPP warranty-
and even though I am mechanically inclined, based on the above it sounds worth it to take to my dealer for the $200 and have them do it.
They are a pretty good dealer- I think they can handle this.

I am real short on time in the next few weeks, and if parts will cost
close to $200 I will take it in-

What parts do you think are broken/needed and what would you do ?

 

I think I just answered my own question... Holy Molly !!! $297 bucks for a regulator- off to the dealer and warranty repair---

 

take the door pannel off and pull the plug from the motor. put the probes from a digital multimeeter in the plug end, one in each wire, key on push window down switch and check for voltage then window up. should have batt. voltage w/switch in both positions . this rules out the drivers door modjule,switch,ground or power supply.

 

Might I suggest the OP go with a factory part? I bought a regulator last year on fleabay new in package. It was the aftermarket brand and it worked literally for a day before sputtering out.

GM part installed, no problems again. Start Saturday morning, you'll be done by lunchtime, the door interior literally falls off. Easy to do.

ZCobra, your time sounds like its worth more than anything you might save. Parts are more expenisve than that... Remember, GM warranty is 200 ded. on the job. Anything else you can take it in and get checked out with the same deductible?

Dealer ( I mean STEALER) replaced the regulator on my drivers side- it cost me my $200 deductible on the GMPP- but the service guy said they charged GM $720 to fix it !!! Can you believe it - the part they said was $480 !

No wonder GM is losing money- $480 parts that forum vendors sell to us for under $300 and $240 in labor---

 

Some people have attributed the window motor failure to using the auto down mode, and the relay does not release, causing the motor to overheat. I never use this mode anymore. I manually hold the button down and release it, so I know the motor is not continuing to try to run.

Also, I have GMPP and actually got them to pay me for the part and did the installation myself. I feel like we both came out ahead. GMPP did not have to pay the outrageous dealer labor cost, it did not cost me anything, and I did not have to leave the car at the dealer.
